Engine Torque

I want to make a fairly accurate car sim, but I don''t really know how the engines work. In fact, I don''t know anything about engines. Basically, I''ve been reading this tutorial. But, I don''t really get it, all the varaibles like RPM and engine torque depend on eachother, and I don''t know how it''s possible to calculate one or the other. Anyway, should I make the engine RPM depend on user input (when he pushes the up button or whatever, it increases the throttle and the engine RPMs?) If I did that, then how would I store the torque curve? There are about 4 gears each with their own torque curve, and I don''t know how to store the values off these curves, or if I should just make keep a few key points in the car''s file, and then interpolate between them. Really, I hardly have much of an idea of what I''m doing, any suggestions on how to work out these values and stuff would be great. Thanks a lot.

I can''t believe it, what a simple error. I never assumed it was anything because I thought 60 / 2 * pi == 60 / (2 * pi).

Well, now I can get it up to about 60m/s, then when it gets to the fifth gear it starts slowing down, but that''s almost undoubtedly a problem with my gear ratios.

Again, thanks a ton for all your help.
